Jakob Stoklund Olesen 9aa6e0a134 Merge MRI::isPhysRegOrOverlapUsed() into isPhysRegUsed(). ...

All callers of these functions really want the isPhysRegOrOverlapUsed()
functionality which also checks aliases. For historical reasons, targets
without register aliases were calling isPhysRegUsed() instead.

Change isPhysRegUsed() to also check aliases, and switch all
isPhysRegOrOverlapUsed() callers to isPhysRegUsed().
